[julia-users] Re: GUI toolkits for Julia: Gtk vs Tk vs others

I would like to add: QML.jl -- 33 commits, 2 contributors The very first release was just tagged. Already useful for simple but beautiful GUI's. C++ libraries need a C++ wrapper. Cxx.jl is still very difficult to install. An alternative, CxxWrap.jl is just becoming available. Uwe On

Re: [julia-users] shell command didn't work

> > what we're used to in Bash doesn't work in Julia. This is because Julia does not shell out to bash. If the documentation is giving that impression, that is not intended and should be corrected. That said, there is support for making tilde expansion work, but it hasn't been ironed out yet:

Re: [julia-users] Almost at 500 packages!

Maybe I missed a a more recent thread but I would like how things are going for the packages organization. It is currently hard to look for a package when you know what functionality you're looking. It is even harder when you look for something general. What about a tag list ? (keywords

[julia-users] Re: Can Julia handle a large number of methods for a function (and a lot of types)?

Hi Oliver, Just a heads up that I've been working on something similar for the past six months or so. I'm fortunate enough to be starting a new project where I have no legacy code and the freedom to play around a bit. I think we have similar ideas: properties are abstract / singleton types in

Of course. And that's the hardest thing: what we're used to in Bash doesn't work in Julia. Thanks.

Re: [julia-users] Tools for creating presentation slides with Julia code?

I've used RISE for a Julia presentation before and I was very happy with that, you can easily switch between presentation style and notebook style for live coding. On Tuesday, 22 March 2016 17:32:05 UTC+1, Douglas Bates wrote: > > On Tuesday, March 22, 2016 at 11:00:13 AM UTC-5, Mauro wrote: >>

[julia-users] GUI toolkits for Julia: Gtk vs Tk vs others

Hello, When it comes to GUI toolkits in Julia, Gtk seems to be the main choice, followed by Tk. At least in terms of development effort: Gtk.jl -- 444 commits, 23 contributors Tk.jl -- 235 commits, 28 contributors PySide.jl -- 35 commits, 2 contributors Although I like Gtk, I'm curious. Is

Glad to know you are up to speed ... Try this in v0.4 and in v0.5-dev: length( methods(Base.call) ) v0.4 gives 1000, v0.5 gives 1 (deprecated) So, Julia is known to work with 1000-fold signatured methods. The fact that v0.5 is better groomed suggests its worthwhile to consider approaching

Re: [julia-users] Re: metaprogramming update variable when slider changes

Instead of a length-one array you can use `Ref` to hold a reference to an object. If you have multiple variables, then using a dictionary to hold the values with either strings or symbols as keys might be the easiest approach. -erik On Sun, Mar 27, 2016 at 1:13 PM, Fabian Gans

I've been pretty happy using Atom with just "language-julia". I've tried Juno: julia-client and ink with the support installed into julia. But, there are many problems and few benefits. Maybe we get too dependent on fancy IDEs. I also install terminal-plus. Just launch a terminal--it

Re: [julia-users] Re: metaprogramming update variable when slider changes

However, be aware that this only works in global scope: function f() z=2.0 change_variable(:z) println(z) end f() will print 2. If this is a problem, you might wrap your variable in an array of size 1. x=[2.0] change_variable(x)=x[1]=3 On Saturday,

I don't think that's the reason, since: ``` if x == 0 r = y/one(x) # Why not just return y? ``` This can only happen if x = 0 or x = 0.0 and y = NaN or x = 0 or x = 0.0 and y = 0 or y = 0.0

[julia-users] Re: Can Julia handle a large number of methods for a function (and a lot of types)?

There are alternative ways to orchestrate your API. Given the always-on-duty nature of your microagents and the fact that (once configured and mapped into the software as a useable description) it is helpful that your information propagators are persistent (oscilloscope A measures properties

[julia-users] Re: Can Julia handle a large number of methods for a function (and a lot of types)?

Assuming your handshaking and signal management is keeping information available in some easy to discern and decode manner and you are not pushing latency issues, Julia should be a good platform for that. Compilation time usually is not a concern -- and you can make your package autoprecompile

[julia-users] Re: hypot question

It's to ensure that the return type doesn't depend on the value of x. If x and y are integers then the return type of hypot1 will be Int if x==0 and Float64 otherwise.

Hello, I'm designing a scheme to control and read out hardware devices (mostly lab instruments) via Julia. The basic idea is that each device type is characterized by a set of features/properties that have a value type and dimensionality and that can be read-only or read/write (a bit like SCPI

Hi David, I think Jude's functionality is pretty orthogonal to julia-client so they function pretty well as distinct, easier to manage packages. julia-client is focused on live code execution and results visualization while Jude is more about getting traditional IDE tools via static syntax
